Super Jet Wine Filter Troubleshooting


Loss of Suction-

There are a few reasons that the Super Jet Wine Filter can lose suction, most of which can be fixed with a simple adjustment. Troubleshooting points to check for:

  • The intake hose is loose on the pump. The vinyl intake tube can get stretched over time and allow air to leak in and stop suction to be created. Simply remove the tube from the fitting and cut off a ½” of the tube and replace on the fitting.
  • The O-Ring on the port fitting has become crimped. This will also cause air to infiltrate the system and stop suction. Remove the port fitting and straighten or replace the O-Ring.
  • The intake hose may be flush against the bottom of the fermenter. Make sure the intake hose opening is off the bottom of the fermenter.
  • The Pump Head is clogged or dirty. Disassemble the Pump Head, clean it, and remove all the debris.
  • The filters have binded (clogged). Stop filtering and replace the pads with the correct level of filter pads, and make sure you are drawing wine from the center of the fermenter (not the bottom to avoid sediment).

Super Jet Filter Won't Prime-

This particular Wine Filter works on a check-valve system. The check-valve is a functioning part of the pump and will deteriorate due to the acidity from the wine. It is easily replaced. By not allowing solid particulate like oak chips etc. to get into the pump your check-valve will last longer. This part will eventually need changing.

Gauge on Super Jet Filter is not Registering-

Due to the acidity in wine, the small plate that registers your pressure will deteriorate and you simply need to replace it. Unscrew the gauge to remove it and replace it with the new one. Make sure you put Teflon tape on the threaded portion to prevent any leaking.

Gauge Shot Up After Installing New Pads-


  • Check to see if you have placed your pads and/or filter plates in the filter housing correctly.
  • Identify the type of wine you are making to the grade of pad you are using. If your gauge rises quickly, this means that your pads are blinding (clogging) quickly. You may need to filter with a coarser pad.
  • Do not start filtering wine from the bottom of your container, especially if you have sediment. The pump could draw the sediment into the pads and quickly blind them. Start filtering about half way down your container.
  • The gauge increases in pressure proportionately to the saturation of the pads. The more saturated your pads get the more back pressure is created, therefore the higher the pressure on your gauge.

    Wine is Foaming-

    The wine is very young and carbon dioxide (CO2) is present. The pump will release this gas simply due to the action of the pump. Release of CO2 from the wine is a good thing; most kits recommend agitating the wine to help release this gas.

    Wine is Leaking Out of the Pads-

    A small amount of leakage is normal from a plate and frame filter, due to the capillary nature of the filter pads. Allow the drip tray to drain into the fermenter you are filtering from.

    If you did not rack your wine and you have sediment at the bottom you may be drawing up some of the sediment and clogging the pads quickly. Rack your wine before filtering.

    Why to Use the Buon Vino Filter Pads

    You should use Buon Vino Filter Pads for your Wine Filter because the micron sizes and consistency of Buon Vino Filter Pads have been designed to give optimal performance when used with Buon Vino wine filters. The flow rate of the pump is designed to work in conjunction with the Buon Vino Filter Pads to give you the best filtration possible.

    It is very rare that a pump will fail on a Buon Vino filter product, the fan will not run and there will be no pumping noise from the pump housing. In the rare event of a pump failure contact Buon Vino at:
